A scold's bridle, sometimes called brank's bridle or simply the branks, was a punishment device used primarily on women, as a form of torture and public humiliation. It was an iron muzzle in an iron framework that enclosed the head. The bridle-bit (or curb-plate) was about 2 inches long and 1 inch broad, projected into the mouth and pressed down on top of the tongue. The "curb-plate" was frequently studded with spikes, so that if the tongue moved, it inflicted pain and made speaking impossible. Wives who were seen as witches, shrews and scolds, were forced to wear a brank's bridle, which was locked on the head of the woman.
